Quantify geographic sampling bias with sampbias}
Human biases play a large role in the data we collect about species. Here we show a simple method to quantify the bias of roads, cities, rivers and airports on species observations of legless lizards in the Northern Territory

Multiple colour scales in choropleth maps with ggnewscale}
Using multiple colour scales can be a great way to visually differentiate between geographic categories on a map. Here, we demonstrate this by creating a choropleth map to represent the density of plant records from the ALA across bioregions in Australia, and add multiple colour scales to differentiate marine and terrestrial records

Download plant species data by hexagon to make a 3D hex map
Making plots eye-catching can be useful for science communication. Here, we show how to make 3D plots in R with the rayshader package by visualising the number of species identified from ALA observations since 2020
